Replit PRD Generator

Create comprehensive Product Requirements Documents optimized for Replit Agent to build complex applications.

When to Use

• Building complex applications with multiple features
• Need stakeholder alignment before development
• Want one-shot autonomous builds (entire app from single prompt)
• Require clear acceptance criteria and testing plans
• Working on team projects that need documentation

PRD vs Simple Prompt

Aspect	Simple Prompt	Full PRD
Features	1-3	4+
Pages/Screens	1-3	4+
User Roles	1	Multiple
Integrations	0-1	Multiple
Development Time	< 1 hour	Hours to days
Iterations Expected	Minimal	Multiple phases

Rule of thumb: If you can describe it in 10 lines, use a prompt. If you need structure, use a PRD.

Procedure

Step 1: Gather High-Level Requirements

Ask the user:

1. What is the product and who is it for?
2. What are the 3-5 most important features?
3. Any specific tech requirements or preferences?
4. Any reference apps or designs to emulate?

Step 2: Define User Personas

For each user type:

• Who are they?
• What do they need to accomplish?
• What's their technical skill level?

Step 3: Detail Features

For each feature, extract:

• User stories
• UI components needed
• Data required
• API endpoints
• Validation rules
• Error scenarios

Step 4: Design Data Model

• List all entities
• Define all fields with types and constraints
• Map relationships
• Identify required indexes

Step 5: Specify UI/UX

• Color palette
• Page layouts
• Navigation structure
• Responsive behavior
• Key interactions

Step 6: Define User Flows

Document step-by-step:

• Happy path
• Error paths
• Edge cases

Step 7: Set Acceptance Criteria

Create testable checkboxes for:

• Each feature
• Overall functionality
• Performance requirements

Step 8: Plan Development Phases

Break into 3-4 phases with:

• Clear goals
• Specific deliverables
• Checkpoint criteria

Step 9: Present Draft PRD

## PRD Draft: [Product Name]

**Complexity:** [Low/Medium/High]
**Estimated Phases:** [Number]
**Primary Persona:** [Name]

## Usage Instructions

1. Copy entire PRD to Replit Agent
2. Use Plan Mode first to review Agent's approach
3. Approve plan and start Phase 1
4. Create checkpoint after each phase
5. Review and iterate before next phase

Ready to proceed?

Step 10: Provide Iteration Guidance

After PRD delivery:

• How to use Plan Mode effectively
• When to create checkpoints
• How to handle deviations

## Replit Agent Instructions

**Mode:** Start in Plan Mode

**Phase 1 Prompt:**
"Review this PRD and create a development plan for Phase 1: [Phase 1 Goal].
Don't start building yet - just outline your approach."

**Build Prompt (after plan approval):**
"Proceed with Phase 1 implementation. Create a checkpoint when complete."

**Subsequent Phases:**
Repeat plan → build → checkpoint cycle for each phase.

Rules

1. ALWAYS include acceptance criteria — Every feature needs testable conditions
2. ALWAYS define data model — Schema before code
3. ALWAYS specify error handling — Every feature's error scenarios
4. ALWAYS break into phases — 3-4 phases with clear checkpoints
5. NEVER leave fields vague — Every input has type, constraints, validation
6. NEVER skip security requirements — Always include security section
7. PREFER reference apps — Concrete examples over abstract descriptions
